drill-assembly的意思|示意

The tangency point of Bottom Hole Assembly is located at where the drill string just touches the wall of the borehole, and the contact force is zero here.

在计算底部钻具组合的受力和变形时，以前一般都是按弯矩为零的条件来确定其上切点的位置。

For a continuous steering drill tool assembly, because there is crew in it, any transient forced deformation has its special characters.

对于连续导向钻具组合来说，由于其弯螺杆的存在，使得其在任何一个瞬态的受力变形都有其独特的特征。

For every piece, the stiff, hollow pipes that connect the drill assembly with the rig at the surface have to be assembled as the drill is lowered and dismantled when it comes up again.

每一段坚实、中空的连接钻取机索导管的冰芯只能被切碎，因为钻取机再次出来时变得更低了也更细了。

A mechanical model for the offset-axes pendulum drill assembly (OAPDA) was established according to the continuous beam theory and the d.

运用纵横弯曲连续梁理论和达朗伯原理，建立了偏轴钟摆钻具组合动力学分析模型。

Argue in public but come home with drill bits and a self-assembly wardrobe.

可以在公共场合争论，但是一起将钻头和自助安装的衣柜带回家。

Numerical simulation shows that the new method is more effective for the drill-string assembly unsuitable to be simplified as a torsion pendulum.

数值模拟结果表明，对不适于简化为扭转摆的钻柱系统，采用基于钻柱扭转杆模型的新方法进行设计可以取得相对较好的减振效果。
